As reported before, Firefox does not have memory problems - it has a feature that is very memory intensive.
To disable this feature, do the following:
1. type about:config in you address bar
2. scroll down to browser.sessionhistory.max_total_viewers
3. set its value to 0 (zero)

Close button at same tab

Okay, so now they placed the close tab button on the active tab itself. I've heard of that being planned. I, however, really don't like that myself. Does anyone know if it's possible to turn off? Because if not, I'm not switching.
There's no reason to not let the user be able to pick the old way of handling a UI functionality that a reasonable amount of people don't agree with.

There's an extension for the alpha already that turns it off.
I like extensions, but sometimes it seems like you have to have 80 of them just to get options that seem like they should be common sense.
-- "What is Internet Explorer 7? Are you saying we can't access the normal internet?" - I love tech support. Really.
So install Leak Monitor. Then you can see the cause of the most severe memory leaks: poorly coded extentions.
Whenever you close a tab or window and a leak is detected, you'll get a message about it. I used it for a few days and discovered several minor extentions I'd been using were causing some very large leaks.
-- The road to tyranny has always been paved with claims of necessity.
Extensions exist in a global context for the process. They can maintain a permanent reference to objects that are never used again, and should otherwise be freed. They may also create cyclic references, in which one or more objects contains references to each other. This creates a situation where the objects are not referenced by an accessible code path, and the reference count can never drop to zero. The result is a leak, and it is an inherint weakness simple of reference counting garbage collection.
Even web pages can create circular JavaScript references that result in leaks. FF isn't alone in this area either. IE has always been vulnerable to memory leaks via JavaScript, theirs are just confined to bad pages. However, FF 3 will have a cycle detector that identifies unused cyclic references and frees the objects. But that still won't fix sloppy extensions that hang on to large objects for no goood reason.
In my experience, Plugins are pretty bad too. They operate outside the scope of the garbage collection and often don't clean up after themselves. For instance, my installation of Acrobat eats up a large chunk memory just for loading, and doesn't let it go after I navigate away from the page. The PDF Download extension helps, but it isn't perfect.

Currently, there is no way to close a tab without first selecting it.
I used to think this too, which is why I used to use the TabX extension. However, since at least Firefox 1.5 I've been able to "middle-click" a tab to close it (without giving it focus.) Once I learned that, TabX was gone.

Question is, does Opera do these features better or will Firefox?
It does. I like Firefox a lot, but i'm not blind - every single feature that it's available in both and works better in Opera. With a fraction of the memory usage, and much faster to boot. Much more stable too - i only had Opera hangning on me a couple of times (both on Windows and Linux) - when it happens, it promptly apologizes and offers you to open the windows you were browsing at the moment of the crash. Priceless!
Also, Oprera has a shitload of functionality not available on FF or not needing extensions (gesture browsing, searches in the url bar, etc...). Those are the reasons it has been my main browser of choice for years now.

Poorly coded extensions definitely are the biggest memory leak problem. I was using forecastfox for a while and Firefox was leaking like a rusty bucket, even with the sessionistory fix. One day, forecastfox popped up with the latest temperature over an hour after I'd closed Firefox. I uninstalled it right then and Firefox has been pretty well-behaved memory-wise ever since; I haven't seen it's memory usage go over 85 mb.
Also, this fix helps too:
1. Open Firefox and go to the Address Bar. Type in about:config and then press Enter.
2. Right Click in the page and select New -> Boolean.
3. In the box that pops up enter config.trim_on_minimize. Press Enter.
4. Now select True and then press Enter.
5. Restart Firefox.

Darin Fisher did this on the trunk in bug 326273. The complexity of the repair, as you surmised, means that Firefox 3.0 will be the first consumer release to contain these changes.
